Data from: Eating down the food chain: generalism is not an evolutionary dead end for herbivores

Danny Rojas, Maria João Ramos Pereira, Carlos Fonseca & Liliana M. Dávalos
The role of trophic specialisation in taxonomic diversification remains unclear. Plant specialists diversify faster than omnivores and animalivores, but at shorter macroevolutionary scales this pattern sometimes reverses. Here, we estimate the effect of diet diversification on speciation rates in noctilionoid bats, controlling for tree shape, rate heterogeneity and macroevolutionary regimes. We hypothesise that niche subdivision among herbivores positively relates to speciation rates, differing between macroevolutionary regimes. We found the rate at which new herbivorous lineages...

Data from: The dynamics of tent-roosts in the palm Sabal mauritiiformis and their use by bats in a montane dry forest

Tent-making bats modify leaves to build refuges. Leaf modification involves energetic and defense costs that should be balanced by the benefits of tent-roosting. The alteration of the leaf’s vascular system reduces the tent’s life expectancy, so to obtain a benefit bats are expected to use tents regularly as long as they are functional and not modify more leaves than necessary. Over two years we documented the dynamics of tent construction and use by Uroderma convexum...
